APPARATUS FOR SORTING OR SEPARATING COINS.

To all whom it may concern:

Be it known thatI, BJARNE CRANNER, a subject of the King of Sweden andNorway, residing at Kongsberg, Norway, have invented certain new anduseful Improvements in Apparatus for Sorting or Separating Coins and Myinvention relates to means for sorting;

. or separating coins, and has for its object 1 an improved apparatusfor this purpose which is of a ver great efficiency.

My invention consists in combination of means and arrangement of parts,which will be hereinafter explained with reference to the annexeddrawings, showing a preferred form of my a paratus, and which will bepointed out in t e claims.

In the drawings, Figure 1 shows a front view of the apparatus, and Fig.2 an enlarged side view, partly in section, of the top portion of thesame.

A is a central, preferably hollow, post secured to a foot B. Around thispost in a screw line is mounted a slope or rail C, on which the coinsare caused to roll down, the slope being carried by brackets C,projecting from the post. On the external side of the slope there is awall or back D, against which the coins lean when rolling down theslope. This wall has a number of apertures E, the height of which isincreasing from the upper to the lowermost one, each of the aperturescorresponding in height to the diameter of different coins. The coinsrollin down the slope and being by the centrii n al force pressedoutwardly against the wal will tip out through one of the apertures anddro into a cup F, there being a number of suc cups, one for each kind ofcoins, placed on the simple construction and of base-plate B or hung onthe post or under-- Heath the slope. It will be understood that theactual height of the apertures should not be made as large as thediameter of thecoins, there remaining a rib at the foot of the wall, sothat the diameter of the coins will have to correspond with the distancefrom the rail to the upper line of the aperture. The upper Specificationof Letters Patent.

part of the slope is made of increasing width and is outwardly inclinedin the manner shown in the drawings, terminating in an incline G, whichextends to the post andforms a continuation of an inclined bottom orabutment within the post, the latter being at this point apertured, asshown. The up er part of the post forms a chute, through wliich thecoins are dropped. On top of the post there is a collar H, and withinthe chute cross-bars K are placed, which to some degree def-er the coinsin descendin to the incline I and prevent them from c oking up the chuteif a great lot of coins is at once thrown into the chute. When a coinslides down the incline I G, it comes into rolling contact with the wallD, and as the latter is helical the centrifugal force will successivelylift the coin from the inclinedrail and force it a ainst the wall,whereupon it will roll down t e rail till it is thrown out through anaperture in the wall.

I claim- 1. In acoin-sorting apparatus, a helical rail on which thecoins ro'll, avertical or nearlyvertical wall at the external side ofsaid rail having coin-apertures therein, and means to give the coinssuch inclined position relatively to the axis of the helical rail thatthey are automatically lifted to roll on edge under the influence of thecentrifugal force.

. 2. In a coin-sorting a paratus, a helical rail I on which the coinsrol a vertical or nearlyvertical wall at the external side of said railhaving coin-sorting apertures. therein, and an incline to give the coinssuch inclined osition relatively to the axis of the helical railthatthey are automatically lifted to roll on edge under the influence ofthe centrifugal force.

3. In a coin-sorting a paratus, a helical rail on which the coins roll?a. vertical or nearlyvertical wall at the external side of said railhaving longitudinal coin-sorting apertures therein, and an incline atthe up er end form- I ing a continuation of the rail a apted to give thecoins such inclination 'relatlvely to the axisof the rolling-path thattheyare automatically lifted'to roll on edge fluence of the centrifugalforce. 1

4. In acoin-sorting apparatus, a helical rail, a vertical ornearly-vertical wall at the external side of said rail havinglongitudinal coin-sorting apertures therein, the successive aperturesincreasin in height, and a continuation of the rail at t e upper endhaving such under' the inouter edgle erein, a chute on the post havingainclination as to cause the coins to be automatically lifted to roll onedge under the influence of the centrifugal force.

5. In a coin-sorting apparatus, a helical rail carried by the same, awal at-the of the rail'having coin-sorting apertures t bottom to directcoins onto the rail and of 'such inclination as to cause the coins toautomatically turn on edge under the influenceof the centrifugal forcegiven by the rail.

' 6. In a coin-sorting apparatus, a post, a

' chute mounted thereon, means in the chute i to preventthe coins fromchoking the same,

.a vertical or nearly-vertical wall, an inclined helical rail connectingthe chuteand Wall,

' said-chute and rail having such inclination as to cause the coins toautomatically turn on edge under the influence ofthe centrifugal forcegiven by the rail.

7. In a coin-sorting apparatus, a' central prost, a hopper mountedthereon, a chute fed on said opper, cross-bars in the chute, an inclinedbottom in said chute, a helical rail forming a continuation of saidbottom and supported by vertical wall at the'outer edge of said rail and0st, a

said post, a vertical or nearly therein.

8. In a coin-sorting apparatus, a central having longitudinalcoinsorting apertures hollow post having a lateralaperture near its top,a hopper mounted on the top, cross-bars mounted in the post beneath thehopper, an incline in the post beneath the cross-bars, a

helical rail mounted on theexterior of the post and forming acontinuation of the incline, a vertical or nearly-vertical-Wall at theouter edge of said rail having longitudinal coin-sorting slots therein,and a receptacle supported by the post in close roximity to each slot toreceive the coins fa ling through said slots.

In testimony that I claim the foregoing as my invention I have signed myname in presence of two subscrlblng Witnesses.
